As shown in fig. 1, the abnormal transaction real-time monitoring system of the present embodiment includes a plurality of acquisition servers 11, a plurality of data exchange servers 12, a distributed computing platform 13, and a plurality of alarm servers 14; wherein:
the acquisition server 11 acquires the transaction data of the transaction server 10 through network communication, and pushes the acquired transaction data to the data exchange server 12 through network communication;

The prior art limitations on database performance can be overcome by collecting the transaction data through the collection server 11. Preferably, the collecting server 11 collects real-time transaction data of the transaction server 10 or the transaction server 10 actively pushes the real-time transaction data to the collecting server 11. By collecting the transaction data in real time, the database does not need to be periodically scanned, and the occupation of the computing resources of the transaction server by scanning operation is avoided.
Preferably, the transaction data collected by the data collecting server 11 is transmitted to the distributed computing platform 13 in real time through the data exchange server 12. Preferably, the distributed computing platform 13 performs real-time parallel computation on the transaction data. Through real-time data transmission and real-time parallel computation, abnormal transaction behaviors can be detected immediately, and abnormal transaction reports can be pushed to workers through the alarm server 14.
As shown in fig. 2, the abnormal transaction real-time calculation method of the present embodiment, which is used in a single calculation server 130, includes the steps of:
acquiring real-time transaction data, and generating keywords and data blocks of each item of transaction data according to statistical dimensions by combining with the real-time transaction data shown in FIG. 3;
marking the transaction data items through HASH values, and marking the data blocks through the keywords; and cache the real-time transaction data in the form of the data block into a storage device of the calculation server 130;
the calculation server 130 reads the data blocks corresponding to the keywords of the transaction data in the storage device to perform analysis calculation to obtain the abnormal transaction report, it is easy to understand that the analysis calculation in this step is a conventional calculation method in the art, and does not belong to the improved part of the present invention, and a person skilled in the art can implement the analysis calculation according to the conventional technical means.
The keyword is used for describing the statistical dimension of the data block, and the data block is used for storing partial information of one transaction data corresponding to the keyword.
For example, the calculation server 130 receives three new transaction data { a1, a2, a3}, each transaction data is labeled by a HASH value and has three statistical dimensions. For the transaction data a1, three keys { k1, k2, k3} may be generated, and three data blocks are correspondingly generated, wherein the key ki is correspondingly used to describe the data blocks.
Preferably, the calculation server 130 performs analysis calculation on the transaction data in a concurrent calculation or parallel calculation manner. In the computation server 130, through configuration of computing resources, for example, one computation instance is used for computing the transaction data, and through three computation instances, parallel or concurrent computation of the three transaction data { a1, a2, a3} can be realized. Therefore, real-time calculation of a plurality of transaction data is realized, and the efficiency of identifying abnormal transaction behaviors is improved.
As shown in fig. 4, the abnormal transaction real-time computing method of the present embodiment, which is used in the distributed computing platform 13, includes the steps of:

and performing parallel computation through a plurality of computation servers 130 of the distributed computation platform 13 to obtain an abnormal transaction report.
The distributed computing platform 13 distributes computing tasks and summarizes computing results. Regarding the consistency of the processing principle of the existing transaction data, only two transaction data { a1, a2} are taken as an example for detailed description.
Referring to fig. 6, one computing server 130 of the distributed computing platform 13 receives the data block corresponding to the keyword Key1 of the transaction data { a1, a2} and performs analysis and computation, another computing server 130 receives the data blocks corresponding to the keyword Key2 and Key3 of the transaction data { a1, a2} and performs analysis and computation, the data blocks corresponding to the remaining keywords are performed by the other computing servers 130 of the distributed computing platform 13, and the processing process of the remaining transaction data may refer to the processing process of the transaction data { a1, a2}, which is not described herein again. The calculation servers 130 perform parallel calculation on some transaction data or some data of some transaction data to obtain calculation results of the data of each part, and the distributed calculation platform collects the calculation results to generate an abnormal transaction report.
As shown in fig. 7, further, the real-time computing method further includes a correlation operation step:
defining a plurality of related operation items { aj, ak, … } in the transaction data { a1, a2, a3, …, ai, … };
caching the complete contents of the plurality of associated operation items { aj, ak, … } into each computation server 130 of the distributed computation platform 13; the step is preferably: each computing server 130 of the distributed computing platform 13 broadcasts the received partial data of the plurality of associated operational items { aj, ak, … } among all the computing servers 130 of the distributed computing platform 13, and simultaneously each computing server 130 receives the data broadcast by other computing servers 130;
and performing correlation operation on each item of data of the transaction data according to a correlation keyword between each item of data of the plurality of correlation operation items { aj, ak, … } and the rest items of transaction data { a1, a2, a3, …, ai, … }, so as to obtain an abnormal transaction calculation result.
Taking the transaction data { a1, a2} as an example, and referring to fig. 8, defining the transaction data a1 as related operation items, each computing server 130 of the distributed computing platform 13 has received partial data of the transaction data a1, and the set of the partial data of all the computing servers 130 is complete data of the transaction data a 1.
The computing server 130 that receives the data block corresponding to the Key1 of the transaction data { a1, a2} broadcasts the data of the data block corresponding to the Key1 among the computing servers 130 of the distributed computing platform 13, and the other computing servers 130 of the distributed computing platform 13 receive the data of the data block corresponding to the Key1 of the transaction data a 1; for the data blocks corresponding to the other keywords of the transaction data a1, broadcast and receive according to the same process, and then all the computing servers 130 of the distributed computing platform 13 cache the complete data of the transaction data a 1.
The transaction data a1 is used as the related operation item, and a plurality of related keywords exist between the transaction data a2, so that the related operation of the transaction data a1 and the transaction data a2 is carried out. When there are multiple associated operation items and multiple transaction data, the process is the same as the above process, and is not described herein again.
The abnormal transaction real-time computing method for the single computing server and the abnormal transaction real-time computing method for the distributed computing platform are applied to the abnormal transaction real-time monitoring system. By real-time acquisition of transaction data and real-time concurrent computation/parallel computation, the abnormal transaction behavior is monitored in real time; meanwhile, the association relation among all transactions is analyzed by combining association operation, so that abnormal transaction behaviors can be identified more accurately.
The above embodiments describe the working principle of the present invention and the process of performing real-time calculation in detail, but should not be construed as limiting the present invention. It is easily understood that the technical solutions according to the present invention may be further modified by those skilled in the art, but any simple modifications or equivalents will fall within the protection scope of the claims of the present invention.
